There's been several changes to European competitions for this season.

From the team who finishes fourth in the Premier League now gaining automatic entry into the Champions League group phase thus no longer having to face a pre-qualifier in August to an additional substitute in extra-time, a lot has happened at Uefa's headquarters over the past few months.

With so much going on, it would be understandable if many supporters haven't been able to keep track of all the changes.

One alteration that had slipped under the radar of Arsenal and Chelsea fans was that of the new kick-off times in the Europa League for this season.
